When it comes to a node getting an IP address from DCHP, when the offer is made, who does the DHCP server send it to? From what I red broadcast is used, but shouldn't the DHCP server reply to the MAC address? Is it that the broadcast IP address is used but the sequesters MAC address is specified?

Sorry, wrong thread.

Great question! You are right in your understanding that the DHCP server uses the MAC address of the requesting device to send the offer. Let's break down the process:

1. **DHCP Discover**: The client (the device needing an IP address) sends a DHCPDISCOVER message as a broadcast on the network because it doesn’t initially have an IP address.

2. **DHCP Offer**: The DHCP server receives the DHCPDISCOVER request. It prepares a DHCPOFFER message, which contains an IP address offer and other network configuration parameters.
